'1'his <br />study involves an evaluation of Ure proposed laading based on prcvious desi�n documents and our site <br />im�estigation with a detemiination that die proposed loading will l�ave no detrimental impact on existing <br />building and associ�ted cotnponcnts. <br />Tl�is analysis assumes that the existing building and associated componcnts have been properly <br />constructed as per the original dcsign and have becn well maintaii�ed. The loads used in evaluatine tl�c <br />adequacy of the installation were deterniined in accordance with the rcquirements of the 2009 <br />Intcrnational Building Code and ASCL' 7-0i (Minimum Design Loads for Building m�d Otlier Structures) <br />for a 3-sccond gust wind speed of S� mpl�. <br />Our study findings sho�v lhat thc proposed antennas and the equipment cabinet are within lhc previous <br />modification design envelope of Ihe supporting mounts and the sleeper frame. Therefore the cxisting <br />building and associated components ���ill be adequate to support the AT&T installation, providcd that thc <br />antenna and equipment are installed in accordvue with our dra���ings (refer to MH Project No. 5100200 <br />SNS6, dated 04/23/11). <br />\Ve tn�st that t:iis report is satisfactory.
